7.8.0

### Electron version

35.1.2

### Operating system

macOs 15.3.2 (24D81)

### Last known working Forge version

_No response_

### Expected behavior

When I build my app, it should work like it does in dev

### Actual behavior

When I build the app using `electron-forge make` and run the final binary at `out/make/electron-forge-help-1.0.0-arm64.dmg`, it errors out on startuo with "Cannot find module 'sharp'":


### Steps to reproduce

- clone the reproduction repo https://github.com/damms005/electron-forge-help
- install deps and `npm start` and confirm it works
- build with `npm run make` and run the executable in `./out/make/...`
- you should get error similar to screenshot provided

### Additional information

It seems #1276 and #1250 have same issues, but they are webpack-based and I am unable to transfer my understanding of them to this vite-based project
